solution:
=>x+11/x+15= x+1/x+3
=> (x+11) (x+3)= (x+1)(x+15) [cross multiplication]
=> x^2+3x+11x+33= x^2+15x+x+15
=> x^2+14x+33= x^2+ 16x+15
=> 2x= 18
=> x= 9

hey...
x+11÷x+15=x+1÷x+3
cross multiply
(x+11)(x+3)=(x+15)(x+1)
x2+3x+11x+33=x2+x+15x+15
take all one side
x2+3x+11x+33-x2-x-15x-15=0
14x+33-16x-15=0
-2x+18=0
-2x=-18
x=9
x+11÷x+15=x+1÷x+3
